Set default Axis/Point

[micheus]

i tried what you said and kind of getting there. But when i set the default axis with enabled tweak tool. The selections still moved with the original coordinates instead of the the new default axis.

I din't used that before, but now you asked about I took a look it.

First, be sure to not be using any of the regular axis constrains (F1,F2,F3).
Then, choose the Tweak->Axis Constraints->Default Axis to apply the Move or Scale operations using it.

Maybe the problem would be you switching to the other constrains (like using F1,F2,F3). That disable the Default Axis mode.

If you intend to use Default Axis constrain regularly, then you may consider to assign a hotkey to it (like [T]). This way you are going to see this indication next to the F1,F2,F3 on top of the geometry window when Tweak is active.
